For a given gas at \( 1 \mathrm{~atm} \) pressure, rms speed of the molecules is \( 200 \mathrm{~m} / \mathrm{s} \) at \( 127^{\circ} \mathrm{C} \). At 2 atm pressure and at \( 227^{\circ} \mathrm{C} \), the rms speed of the molecules will be
(a) \( 100 \sqrt{5} \mathrm{~m} / \mathrm{s} \)
(b) \( 80 \mathrm{~m} / \mathrm{s} \)
(c) \( 100 \mathrm{~m} / \mathrm{s} \)
(d) \( 80 \sqrt{5} \mathrm{~m} / \mathrm{s} \)
